It measures 8 inches by 7 inches by 5 inches and is built to handle airflow splits in residential and commercial HVAC ductwork. A wye branch fitting connects one main duct run to two branch runs at an angle, allowing air to flow in two directions from a single source. This makes it a core component in forced-air heating and cooling systems where duct runs need to divide and distribute conditioned air to multiple zones or rooms. HVAC installers, sheet metal workers, and mechanical contractors rely on wye branches like this to build efficient, low-resistance duct systems. The angled split of a wye fitting reduces turbulence compared to a standard tee, which helps maintain airflow velocity and system efficiency. The Southwark Metal 78875 is fabricated from hot dipped galvanized steel meeting ASTM A653 CS Type B standards, which means the steel base is coated with zinc through a hot dip process for corrosion resistance and long service life. The body gauge on this fitting size range falls at 30 gauge, while the collar is manufactured at 28 gauge for added rigidity at the connection points. The large end features a straight female connection, which accepts a crimped male end from adjacent duct sections. The two smaller ends are crimped male connections, making it straightforward to connect into standard round duct fittings without additional adapters. This fitting works in supply and return air applications and is compatible with standard round duct systems used across light commercial and residential installations.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHot dipped galvanized steel construction per ASTM A653 CS Type B for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eStraight female connection on the large end and crimped male connections on the two smaller ends for easy duct integration\u003c\/li\u003e\n\u003cli\u003eWye branch geometry reduces airflow turbulence compared to standard tee fittings, supporting efficient air distribution\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Southwark Metal 78875 wye branch fitting delivers reliable airflow splitting in round duct systems, with galvanized steel construction and standard transverse connections that simplify installation for HVAC professionals.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 78875\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Wye Branch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 inches x 7 inches x 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel per ASTM A653 CS Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Gauge (8 inches size range)\u003c\/strong\u003e: 30 Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Gauge (8 inches size range)\u003c\/strong\u003e: 28 Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Connection\u003c\/strong\u003e: Straight Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmaller End Connections\u003c\/strong\u003e: Crimped Male\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51120712319282,"sku":"78875","price":21.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304885195.webp?v=1777738911","url":"https:\/\/voomisupply.com\/products\/southwark-metal-78875-wye-branch-8-inches-x-7-inches-x-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
